Bopak Green is an F1 hybrid pac choi bred for speed and reliability, maturing in just 50 days from seed to tender, harvest-ready greens. This organic white-stemmed variety from Johnny's Selected Seeds is frost-tolerant and thrives in cool-season gardens, making it equally at home in spring sowings and fall harvests across most climates. Its compact bush growth habit and 6-inch spacing needs mean you can tuck productive rows into tight garden spaces, and its moderate water requirements keep maintenance straightforward for home gardeners.

Fifty days from seed to harvest is remarkably fast for a substantial pac choi, and Bopak Green delivers without sacrificing plant vigor or flavor. The white stems stay crisp and tender when you harvest before flowering, and its frost tolerance extends your growing season in both directions, from early spring through fall. Cold temperatures below 50°F can trigger premature bolting in seedlings, but once plants reach maturity, they're remarkably stable and unbothered by cool nights.
Pac choi leaves and tender stems are staple ingredients in stir-fries, soups, and quick sautés across East and Southeast Asian cuisines. The white-stemmed, tender growth of Bopak Green makes it especially suited to raw preparations in salads or as a crunchy addition to grain bowls, though its mild, slightly sweet character shines equally in cooked dishes where both the stems and leaves contribute texture and gentle flavor.
No timeline data available yet for this variety.
Start seeds in 128 or 72-cell trays 2 to 4 weeks before your planned transplant date. Keep soil at 55 to 70°F for reliable germination. Protect young seedlings from cold snaps below 50°F, as extended cold at this stage can trigger premature bolting; use row covers or a warm greenhouse to maintain stable temperatures.
Transplant seedlings before they become rootbound or stressed, as stressed plants are more prone to bolting. Harden off seedlings by gradually exposing them to outdoor conditions, then plant into prepared garden beds or containers. Space plants 6 inches apart with 18 inches between rows.
Direct sow seeds in the garden from early spring through midsummer. In southern regions, fall plantings are well suited to this variety. In colder climates, fall sowing works well in protected structures like high tunnels or cold frames.
Harvest Bopak Green before flowering to ensure the best texture and flavor in both stems and leaves. At 50 days, plants should be ready for picking. Cut or snap individual outer leaves and stems as needed, or harvest the entire rosette at once; either approach works, depending on whether you want continuous harvests or a single larger yield.
